DETERSIVE COMPOUND.

There is known to occur in nature ahydrous aluminum silicate to whichhas been given the name Bentonite (see The Non- Metallic Minerals,George P. Merrill, 2nd 5 ed., London and New York, 1910 pp. 246-7), andwhich has up roximately the formula H,Al,Si,O, Ana yses of a number ofsamples of the mineral from difierent sources has revealed variations incomposi- 10 tion, from which it would appear that the precisecomposition of the mlneral depends to some extent upon its source oforigin and the other minerals in the immediate vicinity. Analyses ofsamples from one source have shown the composition 7 Parts.

The samples were of a soft apple green colour, of smooth soapy feel andof laminar structure.

It is known that the said hydrous aluminium silicate has enormousabsorptive power and is capable of forming a colloid or colloidalproduct when incorporated with solvents.

I I have found that the colloid or colloidal product obtained byincorporating the said hydrous aluminum silicate with solvents hasconsiderable technical value when incorporated with salts of fatty acidsin the manu- 40 facture of soap and polishes and dressings,

. such as metal. furniture, floor, linoleum,

- leather, and like polishes, dressings and preservatives.

. As an example of the preparation of the colloid or colloidal product,10 cwts. of the hydrous aluminium silicate referred to may be placed in1000 gallons of water. Absorption of water takes place rapidl and bysimple stirring or agitation a omoe geneous and perfectly smooth colloidor colloidal product is obtained. The hydrous aluminium silicate may beacted upon by of the colloid or colloidal .the solvent inlump, granularor finely comminuted form.

The following exemplifies some of the ways in which the said colloid or,colloidal product may be incorporated with salts of fatty acids in themanufacture of soa and polishes and dressings such as metal, ihrniture,floor, linoleum, leather, and. like po1 ishes, dressings andreservatives.

10 cwts. of the col oid or colloidal prod-' uct produced as describedmay be incorporated in the usual crutching apparatus with 10 cwts. ofsoap, preferably while hot. The resulting absorption product, whichvaries according to the fatty acid present, is found to have anincreased detergent value, is im roved in appearance and cuts and moul sbetter than ordinary soap.

In the manufacture of metal polish, 1 cwt. roduct may be incorporatedwith 1 cwt. 0 sodium or potassium salt of a fatty acid, preferably aliquid member of the fatty series, such as. e. (g, ricinoleic acid. Tothe mixture are ad ed 100 gallons ofa spirit not usually soluble inwater, such as, e. g., turps, benzinc or other suitable grease solvent.On agitation of the mixture the colloid or'colloidal product absorbs thegrease solvent. 5 cwts. of an abrasive, such as silica, are then addedand crutched into the mass which forms an excellent metal polish. Theincorporation of the colloid or colloidal product has the effect ofholding the heavy abrasive and light spirit together within thecolloidal structure im arted to the mass by the colloid or colloidalproduct. It has been found that the addition of acids increases theproperty of holding up; e. g, the addition of 1% of a solution of boricacid was found to give good results.

The incorporation of the colloid or colloidal product with equalquantities of furniture, floor, linoleum, leather and-like polishes,dressings and preservatives of known composition and containing salts offatty acids, considerably enhances the smoothness, homogeneity andequality thereof. Further, the colloid or colloidal product is of suchsmoothness that it behaves to some extent as a polish, and its useeffects economy in the use of higher priced polishing materials.

A very superior polish or dressing for leather and the like may beobtained by incorporating 2 parts of the colloid or colloidal productwith a cream prepared from waxes, solvent and alkali, as, e. g., greycarnauba wax 5 parts, beeswax 5 parts, Japan wax 8 parts, carbonate ofpotash 5 parts and water 80 parts.
